    Hey guys I have a 2006 tundra V8 double cab SR5. I want to change my differential fluid. I need to know if I have a limited slip differential. How would I find this out for my make and model? Also my manual calls for 90 weight rear differential fluid which I cannot find. Does anyone have a Brandon wait they suggest?

    Maybe a local dealership can confirm based on VIN. I used to have a 2006 SR5 double cab V8 as well and it had a limited slip.

    Put your VIN into this link:
    https://www.toyota.com/owners/vehicle-specification

    and it will tell you if you have a limited slip. Other than that, the easiest way is to check the pumpkin for this sticker:

    Make sure you use the lsd additive.

    Yeah absolutely any specific brand of LSD Additive? I know Toyota does not make one that's what the dealership told me.

    I just got a 2006 tundra, also a V8 double cab SR5. I did use the VIN checked on that link. But it is says nothing about the differential, is that means I have a standard type differential?

    On most vehicles that have a traditional mechanical limited slip you can tell by:

    Jacking the rear of the vehicle so both rear tires are off the ground.

    Put vehicle in neutral.

    Rotate one of the rear tires by hand.

    If the opposite rear tire rotates in the same direction, you have a limited slip.

    If the opposite rear tire rotates in the opposite direction, you have an open rear end.

    I used this stuff without issue. If the unit keeps chattering as you turn corners then just add more friction modifier until the chattering stops.

    Current trucks have an anti-spin rear end and use the ABS braking system to apply the brakes to the tire that is spinning faster. They do not have a LSD with a clutch and no option for getting one with Toyota pickups.

    How much K&W friction modifier do I need to add to my 80w-90 gear oil (3.5qt??) = 4oz for friction modifier?

    Also is there any other modifier that would work? for Ford kinds?

    Hey guys so I am doing my Rear LSD differential change. on my new to me 322k miles 2006 2wd Tundra double cab. I am going to use Walmart's 80w-90 gear oil (1 gallon) which is not synthetic. But I need to add friction modifiers for it. How much do I need to add? for my truck it says I will need to add 3.5 qt. I am thinking of adding the K&W friction modifier - This one exactly
    K & W Chemical Trans-X® Posi Trac® Limited Slip Gear Oil Additive -- Part # 402508

    Thanks.
